IMPROVEMENT IN PAPER BOXES.

Specification forming part of Letters Patent No. 158,134, dated December 22, 1874; applicatian filed November 14, 1874.

To all whom it may concern;

Be it known that I, EDWARD D. F. SHEL- TON, of Birmingham, in the county of New Haven and State of Connecticut, have invented a new Paper Box; and do hereby declare the following', when taken in connection with the accompanying `drawings and the letl ters of reference marked thereon, to be a full,

clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure l, perspective view 5 Fig. 2, diagram ot' the blank. from which the box is formed; Fig. 3, perspective View illustrating the method of folding the blank 5 Fig. 4, vertical central section; Fig. 5, plane central section. l

This invention relates to an improvement in the manufacture of paper boxes or cases; the object being to form the case from a single piece of paperclosed by the peculiar cut upon all sides, save one, which is provided with a tuck.

The blank is rst cut from suitable paper or material, as in Fig. 2, the broken lines denoting the lines of fold or bend.

The two sides A A are turned up, and extremes brought together and secured, as at a, Fig. 3. The intermediate portion B forms one side, the two parts A A two other sides, and the parts C C unite upon the fourth side. Next, the flaps D D are turned nearly over onto the intermediate part E, as seen in Fig. 3; then the flaps F F are turned up so as to pass within the two sides A A; then. the parts D D and E are turned toward and passed in between the sides A B C until the flaps F have fully entered within the sides A, so that the part G will close that end, and form the fth side or one end of the case, the part E completing the fourth side within the parts G. The flaps D are then turned back against the sides A, the ap H protruding at the other or open end of the box. Then the aps I I are turned inward to close that open end, and the aps H and L turned down over the flaps I, and the end of the flap L passed through a slot, a, in the ap H, as seen in Fig. 4.

This method of cutting and folding the blank produces a strong and durable ease, with all the angles securely closed, and with but a single tuck.

I do not broadly claim a box made complete from one piece of material by several folds, as such, I am aware, is very old; but

I claim as my invention-.-

As an article of manufacture, the box herein described, consisting` of a blank cut from a single piece to form the principal sides B E and A A, and the ends G I, with the auxiliary sides D D, and aps G C, F F, and L H, folded and secured substantially as specified.
